Abstract(s)
A oliveira é atualmente a cultura que ocupa a maior superfície agrícola em Portugal e a exploração dos seus frutos reveste-se de grande importância socioeconómica. Existe pouca informação disponível sobre as condições edáficas em
áreas cultivadas com olivais no Nordeste de Portugal e como elas exercem influência na distribuição e desenvolvimento
da cultura. Dessa forma, este estudo visa contribuir com a atualização da informação existente através da identificação
das principais características edafoclimáticas das áreas olivícolas na Região. A informação de base para o estudo incluiu
como fontes principais a Carta dos Solos e da Aptidão da Terra do NE Portugal, a Carta de Uso e Ocupação do Solo e a
Carta Administrativa Oficial de Portugal. O olival cobre aproximadamente 105 mil ha no NE de Portugal e é a cultura
que ocupa a maior área agrícola da Região. Os solos sob olivais são geralmente pouco profundos, pedregosos, ácidos
e pobres em matéria orgânica, grande parte situando-se em terrenos declivosos. As oliveiras estão bem-adaptadas aos
condicionalismos edafoclimáticos regionais, mas é necessário implementar práticas alternativas que promovam uma
melhor gestão dos pomares, para o que é importante aprofundar o conhecimento dos solos das áreas de olival.
The olive tree is currently the crop that occupies the largest agricultural area in Portugal and the exploitation of its fruits is of great socio-economic importance. There is little information available on edaphic conditions in areas cultivated with olive groves in Northeast Portugal and how they influence the distribution and development of the crop. Thus, this study aims to contribute to the updating of existing information through the identification of the main soil and climate characteristics of the olive growing areas in the Region. The basic information for the study included as main sources the Land Aptitude Charter of NE Portugal, the Land Use and Occupation Charter and the Official Administrative Charter of Portugal. The olive grove covers approximately 105 thousand ha in NE Portugal and is the crop that occupies the largest agricultural area in the Region. Soils under olive groves are generally shallow, stony, acidic and poor in organic matter, most of which are located on sloping terrain. Olive trees are well adapted to regional soil and climate conditions, but it is necessary to implement alternative practices that promote better management of orchards, for which it is important to deepen knowledge of the soils of olive groves.
